ToV ali whom t mttyconcern: Y

Be it known that we,MAx Gr'rssrr and RICHARD BAEGER, subjects of the German Emperor, residing at Chemnitz and Ehrenberg, near Altenburg, in the Empire of GerV many, respectively, have invented certain new and useful Improvements in, Apparatus for Separating Wort from Mash, oi which the following isa specification. Y This invention relates to a new and assisi improvement in apparatuses for separating the dra from yvort by centrifugal action.

The invention-aims primarily to' provide a lInaehine of the above type embo ying in combination with the centrifugal apparatus a grading apparatus wherebyfthe drai, albumerioids and otherimp'urities will be suecessively se arated from the wortin accordance with t eir specific gravitis.

In the annexed drawing an apparatus serving for' the vpurpose above referred to is shown.' v Y Figure l'ss vertioal section of the Inachine and Fig. 2 a toprview thereoipartially in horizontal section.

As to bessen from the drawin i is a shaft 'adapted to'be rapid] revolved y means of Keys( to'said shaft is a hub 3 the pulley 2. togwhioh are ixedfour or six downwardly curved ilatirms 4, each of which terminates in a flat plate 5. The plates 5 support a thick' annular gert 6 provided with a rim 7, a'nd to the sai part 6 is fixeda non-perf@ A' rated, preferably eyiindrical part 8, a ti ht joint being made between the parts 6 an 8.

"bottoni is tbu'sformed, 'and thieehamber surrounds'a removable rforated wall 9 in ameter of Wbih is smaller than that of the ier space 1G is left free 'between the latter the Wall 9.- An essential-eatureof the appa# ratus consists in thefact that the rforated wall 9 forms with the horizonte planean. anglevvhich is not greater than the angle of :friction at which the returns are thrown against ,the said wall.- 'To ailow of f1orising'y on the inner surface of thewall, slayer of returns whioh is innitelyfthirr alt'the u per part and increases Vin `thickness tort the ower part, ,the ring fis provided with an inwardly projecting ilalnge rfof), the* width of which is equal to the greatest thickness which it is proposed to t ive to the said layer;

The height of the pe' orated wall 9 is rei ereblysomewhat less than the height o the Wall 8, and fixed to 'the u per partof said Wall 9 is a metal ring o r isk', the outer. diameter of which is' suoli that a certain amount of s aee is left between the said disk and the Wa 8. The aperture in the center of the disk 2'? is of such size as to afford space for the distributer 15 16 and the pipe 12 hereinafter referred to-" The disk 27 supports aseries of rings 30, 31,- 3 2 and 33,'the ring' 30 being preferably fixed to the disk Whereas latter. T he wall is provided with vertieal, radial plates 37, which preferably extend through the entire Width o the Space mand are prolonged upward in the ehamberd. to ther annular eover 24. Y The rings Si), 3l 32 andlare also providedl with radial plates 69, 7G, 7l and72, which are located iii-stabgered relation and are also staggered withv respect to the plates 3?, as shown in Fi 2.` By this means a series of se arate cham ers 'is formed thepresenee of W ich not onlyineures a 'steady flow of the passing Wort but also prevents' unintended displacement oi the 'rings 31, 32 and 33. The ring 31 is providedat its u per part with an annular iiange.

34 einst w ich they ring 32 and the ange 35 o the Vring 33 abut. The ring 32 is pro vided with a. Harige 36 on which the ring 33% resta Thefwall 8 and the rires 30, 3l, 32

' and 33 thus form four annular chambers '64,

Thev distributor l5 16, which is arranged below the mash-supply pipe or hopper 14; may be'of any suitable type. In the forni of oonstruction illustrated it clonssts of a disk 15 provided; radial flanges 16. In some eases itmay be desirable that'the distributor ebouldrmalre a greater or less number of revolutions than said walls Sand 9, in order that the mash discharged from the distributor shall not always be thrown against the same portions ofthe Wall 9 butV shall always :strike the rings Si, 32 and 33 simply rest upon the.

different portions of' the latter and thus bc t more uniformlydistributed. 1n the form of construction illustrated in Fi rs. 1 and 2 the distri buter l5 16 is fixed to a s iaft 3h in order to allow lol` its being revolved more rapidly or more slowly than the wall 9. The bearing 23H of thc shalt 25S is arranged in a bracket 4U, thc latter being fixed to a beam 41 which rests on and is fixed to, a flange 42 with. which the outer jacket 17 is provided. A worm wheel 43 is fixed to the shaft 38 and meshes with a worm 44 .fixed to a shaft 4G, which has bearing in supports 45 which may be integral with the bracket 40. To `the shaft to is fixed a pulley 47 which is connected, by means of a drivingscord or the like with a pulley 4S fixed to an intermediate shaft 2t). To the latter is fixed a pulley 4t) connected by means of a drivingbelt orthe like with a pulley 2t) fixed to a second intermediate shaft 51, and a pulley 5() mounted on the latter is connected, by means of a driving belt or the like with the pulley 2 on the shaft 1. It is obvious that by using pu lleys of suitable diameters the distributer can be caused to revolve more rapidly or more slowly than the wall 9. j

Within the jacket 17 there is arranged an 'inclined floor 28, down which the returns` slide from the wall 9 to the trou rh 52, a screw conveyer 53 being arranged in t 1e latter.

The jacket 17 is preferabljv so closed externally, that if `desired the circulation of air due to the rotation of the walls 8 and t) can be almost entirely prevented. ff circulation of air is desired, air-apertures provided with suitable closing means can be arranged in the jacket 17.

The centrifu al apparatus operates as follows: The masi passes through the tube or hoppcr14 on to the rapidly revolving disk 15 and is then acted on by the guides or vanes 1G and thrown against the inner surface of the revolving wall 9. As has been mentioned, the wall t) forms, with the horizontal plane, an angle which is not greater than the angle of friction ot the returns thrown against the wall t). By the term angle of friction is meant thc angle at which the returns strike the inner surface of the wall t) when thrown from thc distrilmtcr 157 lti. 'lo secure the desired layer of returns upon the inner surl'ucc of thc wall El, thin at the top thereof and gradually increasing in thickness toward the lower part, this` angle ol' friction should beI equal lo the angle formed by intersection of the plane' oll said distribution with said wall und mayV be influenced by the speed at which the distributcr is rotated with relation to said wall and also by the condition ofthe mash. 'lhc rclurns therefor(I slide down the wall t) until they reach Atho flange-tit), by which they are prevented from leaving the centrifugal chamber. 'lhc action described continues until a layer of returns IS is formed on the l inner surface of the Wall 9, the thickness of this layer being infinitely small at the upper part, but increasing toward the bottom until it is equal to the width of the flange (it). The heavy albuminous .substances separated during the centrif'uging process pass through the upper part of the wall 9, together with some of the wort. At the upper part of the wall t) only slight resistance is offered to the passage of said albuminons substances, and the latter are thus afforded no opj'iortunity of' being retained by the returns in such a manner as to prevent the continued passage ol' the liquid constituents of the mash. That portion of the liquid which comes into contact with the lower part of the layer 18 contains no coagulated albinninoids, so that obstruction ofthe said lower part by albuminous substances cannot take place. The liquid which passes through the perforated wall t) together with the albuminous bodies enters the space 10 and is thrown against the nonpcrforated wall 8 which revolvesfwith the wall 9. This liquid more particularly enters the chambers formed bythe plates 3T (Fig. 2.) Vtihen, in the course of the action described, the layer 1b' has been formed, the inner surface of the lattermakes with the horizontal plane an angle which corresponds with the angle of friction'of the continuously supplied freshly arriving returns or mash. Under the inuence of centrifugal force the latter slide down the inner conical surface 19 of the said layer and con-- tinuously discharge into said layer the wort with which they are mixed; centrifugal action causes this liquid to pass through the layer 18 and through the holes in the Wall 9. In the chamber 10 the albuminoids which have passed through the perforated wall 9 with the wort are for the most part depositedhy centrifugal action on the wall 8. The clear wort is compelled to pass upward from the chamber 10 into the chamber 64 and thence through the apertures 73 in the rin 30 to the chamber-65. ln the latter the al )uminoids ofV lower specific wei ht still contained in the wort are deposited i centrifugal action on the inner surface of tllfe ring 30, and are prevented from passing upward by th'e cover 24. From the chamber the wort passes through the apertures 74 in the ring 3] to the annular chamber 6o in which the action described with reference to thc chamber (i5 is re icated; that is to say the albuminoids and other impurities still contained in the wort are deposited by centrifugal action on thc nner surface of the ring .'51, the wort flowing upward through the apertures T5 in thc ring 32 to t'he chamber (i7. Yln thc hitter thc liner impurities Istill contained in thc wort arc driven against the surface ol' thtI ring 2&2. Finally thc wort passes through thc :ipcrt urcs 7G into the chamber (iN surrounded by the ring 33 and is driven against the latter and dischargedthrough thc pipe L25. rlhc ret urns zo emm'ifugug of the Secund wort fan im pm vfwiied by i?
